Solution 1

Its better you set the Cascade relationship between both the tables.

So, when once you delete the primary key data it will delete the foreign key rows from the foreign table.

Solution 2

Create a stored procedure and mention it as DeleteCommand

Otherwise, try On Delete Cascade for new tables or enable cascade delete for existing tables.

Solution 3

Your best bet is to write a proper datalayer, and have more control over your SQL. You may be able to create one SQL statement that does both things, just put GO between them. But, I don't know how this rubbish works, I never use it, because I prefer well written code.
